Glucose blood test: what your result means
Glucose measures blood sugar, the body's main immediate energy source. It is central for metabolic and diabetes monitoring.
- Standard unit
- mg/dL
- Reported in
- mg/dL, mmol/L
What does high glucose mean?
Higher values may suggest reduced glucose regulation. What counts as high depends on the reference range printed on your lab report, because ranges differ between laboratories.
What does low glucose mean?
Lower values may suggest low available blood sugar. What counts as low depends on the reference range printed on your lab report, because ranges differ between laboratories.
Glucose units and conversion
Mediki shows glucose in mg/dL. Labs may report it in other units; Mediki converts them automatically so results from different labs line up on one chart.
| Unit on your report | Convert to mg/dL | Convert back |
|---|---|---|
| mmol/L | 1 mmol/L = 18 mg/dL | 1 mg/dL = 0.05556 mmol/L |
Convert a value from your report with the blood test unit converter.
Why track glucose over time?
A single glucose result is a snapshot. Comparing it with your earlier tests shows whether a value is stable, slowly drifting, or responding to a change in treatment or lifestyle, which is often more useful than one number on its own.
